To all 'whom z't'maiy concern:

Be it known that l, JULrUs C. Hm'rz, a

'citiaen of the United States, and a resident tacle, 'Water fed to the receptacle and the same then revolved rapidly so as to force the Water through the clothes.

It has as its object the construction of a machine adapted to use this centrifugal "principle, and inl which there is provided la circulation system for the washing or rinsing water so that a continuous feed of water is not necessary.

I accomplish these objects as stated, and obtain various-other advantages as will be detailed, by that certain construction and arrangement of parts to be hereinafter more specifically pointed out and claimed.

desired kind, at the upper end of which is the ,journal 2 for the shaft 3 of the power pulley 4. The shaft `3 fits into a hollow shaft 5, which .extends clear to the base of 4the machine.

Inside o'f the outer frame piece is a cylin.- drical shell 6, having an odset formed in it by an annular angle bar 7 which finds a seat on a cylindrical drum secured at the base of the machine. Set inside this latter shell in the base of the machine is a round trough pan, with flaring sides 8 extending up under the oifset 7 so that all water running down inside the shell 6 from above will fall into the trough.v The trough 9 is circular in shape, and its inner wall 10 extends inwardly and upwardly in a cone shape around the axis of the hollow `shaft 5 already` mentioned.

As shown in Fig. 2, the portion of the shell 6 above the odset at 7 may be formed of two parts 6a and 6b, hinged togetherv at 6". The otherxend of the two'halves are bolted together at 6d. This shell can be swung open to give access to the clothes receptacle to be hereinafter described the flanges at 7 vswinging away from'the ower portions 7a.

The hollow shaft 5 at its lower end has the 'll-shaped branches 11, 11,` whichl extend down into the trough 9, and are provided at their extremities with the scoop mouths 12, 12, so that when the shaft rotates rapidly, the mouths will scoop up water which will be forced upwardly through the branches into the shaft, and up the shaft to the washer as will be described.

The shaft is supported on a post 13, having a cone-shaped end 14, which has a bearing in the roller bearing socket 15 in the base of the machine. The shaft has also a -funnel shaped guard 16, that is secured to it above the branches 11 to prevent splashing of Water. If any water should rise up or splash up over the inner wall 10 of the trough 9, the small chamber between these walls and the post 13 will become lled with y water without doing any damage.v

Some outlet pipe 17 is provided for draining out the trough.

The receptacle for clothes is securely bolted onto the hollow shaft 5, and comprises a circular imperforate bottom plate 18 and a cylindrical side wall 19, which is provided with many apertures V20 for the escape of water driven centrifugally through the clothes.

The shaft has bolted onto it at 21 a number of vertical radial vanes or beaters 22. These beaters are all of the same width and a cylindrical screen 23 is secured around their outer edges to prevent the clothes from getting between the vanes. The vanes are also bolted at 24 to the bottom. plate18 of the receptacle.

As a top for thel receptacle, a circular plate 25 is provided, domed at the center, and having an annular channel bar 26 around its peripheryto seat over the edge of the cylindrical portion 19 of the receptacle. Hooks 27 on this top engage a cord 28 that is passed up over sheaves 29 29, on the frame, and provided with weights 30, 30. Similar hooks 31 are mounted on the side pieces of the frame l, to hold the ends of the cords When the Vtop is closed dow'n overv the receptacle. y l l The top When lowered into closed position is locked onto the shaft 5 bym'eans of a taperedl screwthreaded sleeve' 32, which is split (not shown)v so as tdbe' contractible. A screw-sleeve 33, tapered inversely, Serves to compress 'the sleeve so as to frictionally loci it against the shaft. top of the receptacle, and the shaft has apertures35, 35, located'belovv the vplug to feed Water from the shaft to the vanes. need not be the only openings into the receptacle from the shaft, but care must be vtaken that -plenty of Water reaches the top of the 7receptacle.

vThe operation-of the device is as follows: The cover or lid 2,5 is raised and clothing packed into the chamber between the vscreen 23 and the sides 19. Hot and soapy water is poured in the space inside the screen 23 and into the round trough pan -9, and the shaft 5 rotated. Thisrotation should be fourteen hundred revolutions to the minute, 6r more, and will result ina raising of Water, throu the shaft, a forcing of it through the c1051- jing, and afalling back into thetrough,

Athereby setting up a circulation.Y Soap may be placed Within the screen 23 if desired.

When'was'hing is completed, the Water is let out at 17, and rinse water inserted to rinse the clothes, and the clothes may be dried, ready lfor ironinggby revolving the machine Without 'any-'Water in it. It is obvious that the` mechanical expedients employed in the designing of this Washer may be considerably modified by thaty use of equivalent structures. v

The clothes should be soaked 'before being packed in as uniformly as possible so that they do not become unequally washed.
